Guzman has escaped from prison once before, in 2001. Prior
to his arrest again last year, the US Justice Department
considered him "the world's most powerful drug lord." He heads
the Sinaloa Cartel, which the department
describes as one of the world's "most prolific, violent and
powerful drug cartels."

Trump has built his nascent presidential campaign off harsh and
controversial rhetoric about Mexico, so it's no surprise that he
jumped on Guzman's escape. He has accused the Mexican government of sending
rapists, drug runners, and other criminals to the US.

In a string of other tweets on the topic Sunday night and Monday
morning, Trump said, "I told you so!" and further raged against
the Mexican government:

Mexico's biggest drug lord escapes from jail. Unbelievable corruption and USA is paying the price. I told you so!
